UNITED STATES PATENTS 10 Claims, 6 Drawing Figures 2,024,588 12/1935Lesser ..70/371 X LOCK MEANS FOR RELATIVELY SLIDABLE CLOSURES Theinvention relates to the novel structure of lock means for sliding doorsor windows. Such closure ele ments are conventionally mounted at leastin pairs within a jamb on trackways in such a manner that their relatededges overlap when in closed position and which may be moved relative toeach other into open position.

Most sliding closures comprise at least two panels, each consisting ofrelatively narrow frame members, generally extruded from relatively softaluminum, which carry a large pane of glass. One or more of the panelsmay be stationary, and the movable panel may slide either outside orinside of the stationary panel.

Heretofore, it has been extremely difficult to provide fool-proof meansto lock such closures in closed position. Hasp locks, bolts and rigidmovable bars extending between a door frame and jamb have conventionallybeen used to lock such closures, but have been found easy to jimmy byslightly lifting the door relative to the track or by pulling themounting members from the relatively soft aluminum extrusions, or tointerfere with door operation, or to be unsightly, or not adaptable tosome makes or styles of doors because of structural variations.

In the present disclosure there is provided a lock element that isremovably mounted on one of the pairs of closures in such a manner as tobe abutted by the related closure. Key actuated means is carried by theelement to secure it mounted.

It is therefore an object of the invention to provide lock means of thecharacter referred to.

Another object of the invention is to provide a novelly constructed lockbar for a slidable closure.

Another object is to provide a lock element with key actuated means toengage in a slidable closure.

Another object is to provide a lock structure of the character referredto which is not expensive or difficult to manufacture, which may beapplied to a slidable closure readily, which is adequately versatile tolock all conventional sliding glass doors, and which is very efficientin use.

Other objects and advantages of the invention will become apparent withreference to the following description and accompanying drawings.

In the drawings:

FIG. 1 is a fragmentary inside elevational view of a closureinstallation, showing the lock element in place.

FIG. 2 is a vertical sectional view taken substantially on line 2 2 ofFIG. 1.

FIG. 3 is a horizontal plan view of the lock element, as viewed alongline 3 3 of FIG. 2.

FIG. 4 is a detail sectional view of the key-actuated lock, viewed alongline 4 4 of FIG. 3.

FIG. 5 is a fragmentary detail sectional view similar to FIG. 2, showinga modified embodiment of the invention including an interconnectedbracket for selfstorage of the lock element when in operative position.

FIG. 6 is a fragmentary detail elevational view of the modifiedembodiment shown in FIG. 5, except the lock element is shown in solidlines when in stored position and in dotted lines as the lock element ismoved from operative to stored position.

Referring to the accompanying drawings which show an exemplaryembodiment of the invention, the present lock means'is designedprimarily for use in association with horizontally disposed slidingdoors or windows, 11 and 12. As shown, these closures may each comprisea glass panel 13 surrounded by a metallic frame 14, frequentlyfabricated from extruded aluminum. The closures are mounted side by sidein a jamb or casement frame 15, which includes a sill 15a, havingsuitably formed horizontal tracks 16 and 17 along which the closuresslide. Either closure 11 or 12 may be moved relative to the otherclosure into an open position, and when in their closed positions, theircomplemental vertical margins 18 and 19 overlap.

In order to lock the closures against relative sliding movement whilethey are in their closed positions, there is provided a removable lockelement, generally indicated at 21, which is best shown in FIG. 3. Thislock element comprises an elongated body 22, preferably of square barstock, having at one end a flange 23, which is perpendicular to one facethereof. Flange 23 carries on its outside face a stud 24, and a similarbut heavier stud 25 projects from the back surface of the body at somedistance from the flange 23. Adjacent to the other end of said body is abarrel type key-actuated lock 26.

As best shown in FIG. 4, the lock 26 comprises a sleeve 27 that issecured in an aperture 28 in the body 22, as by means of a set screw 29.A lock barrel 31 is rotatable in sleeve 27, it normally being heldagainst rotation by conventional key-actuated tumblers (not shown). Therear face of sleeve 27 is formed with a non-axially aligned circularprojection 32 which is apertured to receive therethrough, for rotation,a stem 33 carried by the lock barrel 31. Mounted firmly on the stem is alocking eccentric 34 which is so arranged that when in non-lockingposition it aligns with the projec' tion 32.

In use, the lock element is laid against the inside face of the outsideclosure 11, with its flanged end in substantial abutment with the edgeof the inside closure 12. To insure proper positioning and attachment ofthe lock element, the edge of closure 12 has a hole 35 to receive thestud 24 and the inside face of the outside closure 11 has a pair ofholes 36 and 37 to receive, respectively, the stud 25 and the circularprojection 32 andlocking eccentric 34, the latter at the time ofinsertion into the closure hole being in its non-locking position. Whena key, inserted in the barrel 31, is rotated one-half revolution, theeccentric 34 is carried into locking position behind the wall 14a offrame 14.

Compensation for variances in the thickness of the wall 14a is affordedby re-adjustment of the position of sleeve 27 upon manipulation of theholding set screw .It will be observed that when the lock element issecurely positioned as above described and locked, there is provided apositive abutment lying in the path of each closure member so as toprevent their sliding past one another.

When the lock element is not in use, it may be stored in a bracket 38attached to the inner closure 12, as shown. If desired (holes notshown), this bracket may comprise a saddle having therein holes of thesame size and shape and spaced apart in the same manner as closure holes35, 36 and 37, respectively, to accommodate stud 25, circular projection32 and locking eccentric 34, respectively, so that the lock element maybe removably secured in the bracket by a half revolution of the key,thus moving the eccentric into locking position, as described.

Referring to the modified embodiment shown in FIGS. 5 and 6, the lockelement 21a is substantially similar to lock device 21, except the rearedge of the flange 23a is chamfered and a hinge pin assembly 39 isprovided for connecting the lock element to a modified storage bracket48. This modified storage bracket includes a saddle 40, an angular strap41, and a guide 42 and stop member 43.

In use, the modified lock element is unlocked from the closure, slidaway from the closure on hinge pin assembly 39 along guide 42 until stop43 is reached, then pivotally swung upwardly and moved toward theclosure and nested in the saddle 40 for storage. To reinstall the lockelement on the closure, the storage procedure is reversed.

While I have described preferred embodiments of my invention, the devicedescribed and illustrated is not intended to be restrictive, as manychanges in the structure can be easily accomplished without departingfrom the spirit or scope of my invention. Accordingly, I do not desireto be limited to the exact disclosure described.
